Y. Gotoh et al., Synthesis of titanium carbide from a composite of TiO2 nanoparticles/methyl cellulose by carbothermal reduction, MATER RES B, 36(13-14), 2001, pp. 2263-2275
Titanium carbide (TiC) was synthesized from a composite constituted of nano
-sized TiO2 particles (ca. 5 nm in diameter) and methyl cellulose (MC) via
carbothermal. reduction in an Ar flow. The composite was converted into tit
anium oxycarbide by heating at 1050 degreesC. With the increase of heating
temperature, the lattice parameter of the titanium oxycarbide phase increas
ed while the oxygen content in the specimen decreased, especially above 130
0 degreesC. That is, low oxygen content (0.60-2.32 wt%) TiC could be prepar
ed from the composite by heating above 1300 degreesC, which was a considera
bly lower temperature compared to that employed in the conventional carboth
ermal. reduction methods that use a mixture of TiO2 and carbon powders. (C)
